When a plug is to be fitted to a first connector from one side and a plug is to be fitted to a second connector from the other side of an optical coupling device, the first connector and the second connector shift in an X direction to ease stresses working on an internal optical fiber. Therefore, stresses working on the optical fiber can be eased without having to extend a length of the internal fiber, and accordingly it is made possible to reduce an overall size of the optical coupling device.
